Preheat the oven to 350 degrees. Peel the apples and remove the cores. Cut the apples into bite sized pieces. Pour the lemon juice over the apples and place them in a baking dish. Combine the bread dice, brown sugar, melted butter, cinnamon, nutmeg and salt in a bowl. Toss the ingredients to distribute the ingredients evenly. Place the bread mixture on top of the apples. Bake for about 45 minutes or until the top is golden brown and crusty. Let cool slightly, but best when served warm.
